Thin as a paper battery, the capacity of more than 15 Apple batteries, the future of mobile phones can also be as thin as paper?

What is a paper battery?


A paper battery is a battery that uses paper as a carrier. The paper battery is a special ink made of silver and carbon nanomaterials. It is coated on paper to make a “paper battery”, which brings hope to the light and efficient new energy storage.

　　With the Samsung Galaxy Fold, Huawei Mate X, Softball FlexPai and other folding phones came out. Folding screen mobile phone can give us excellent visual viewing effect, while the thickness of the body and standby time have always been difficult to overcome. In a single-screen state, the thickness of the body is still much higher than that of a regular-sized mobile phone. The main reason is that the size of the camera is limited, and the size of the battery is limited.

Recently, the University of Linkoping (Linkoping) in Sweden has developed a super battery Power Paper, also known as "paper battery", which broke four world records.

The battery has an extremely thin thickness and excellent ductility and stability, and it can be kept in good condition after repeated folding. Although the battery is small, its capacity is 26,800 mA, which is about ten times the capacity of the iPhone battery to ensure long-lasting battery life.\

The realization principle is as follows: the conductive polymer is rationally proportioned with plant cellulose, glycerin and the like to achieve a battery effect.

　　Power Paper has now received $280 million in funding for the overall implementation of research and mass production. Does such a paper battery really have such a large capacity..
